Sequentially Cohen-Macaulay monomial ideals of embedding dimension four
Sarfraz Ahmad, Dorin Popescu
Abstract
Let I be a monomial ideal of the polynomial ring S=K[x1,...,x4]
over a field
. Then
is sequentially Cohen-Macaulay if and only if
is pretty clean. In particular, if
is sequentially Cohen-Macaulay then
is a Stanley ideal.
